I have a question about that. Your measurement of the pollution linked to automobiles, trucks, and so on—not the one on CO2 but the other one—are they in the air that we breathe or is the pollution coming from the cars themselves in Canada? Because there is a big difference. A lot of air pollution is coming from the United States, so when we say that it's decreasing, are we taking as an indicator the actual air that we use or the pollution coming from the cars in Canada?
